I came to know about this "Vada" by a very dear friend of mine which she makes it with leftover dal.
Fortunately, today I found one bowl of leftover dal was sitting in my fridge.  A thought of trying those Vadas came to my mind. It was definitely a wonderful way to use leftover dal. I tried it and they came out very well. Nobody was able to  judge that they were vadas of leftover dal of last night. I served these Vadas as evening snack with tea and we all enjoyed a lot  .....
